Seeking a Saint in the Snow: the Eldest Son of Northern Liang Seeks to Conquer the Sky

If there is no good luck, I will create my own situation. If there is no force at hand, I will attack the sky with my strategy. Traveling back in time to Xu Zi'an, the non-existent eldest son of King Xu Xiao of Northern Liang in "Snow", he faces a hellish beginning: he is born with a broken heart and will live no longer than twenty-five years; the Liyang court is watching with eager eyes, and the Beimang cavalry is waiting for the day; his younger brother Xu Fengnian is still young, and Beiliang's 300,000 cavalry are troubled by internal and external troubles. There is no system, no force, only military theory and historical knowledge from modern times, and an omniscient perspective on the original plot. Xu Zi'an's choice is: to play chess in the world with his weak body. When he was five years old, he proposed a plan at Hulukou, strangled and annihilated Beimang's eight thousand cavalry on three fronts, and Beiliang was shocked. At the age of six, he founded Tiangongfang, improved the curved shaft plow, developed firearm mechanisms, and integrated modern technology into the cold weapon era. At the age of seven, he established the Yanyu Tower and weaved a world-wide intelligence network in Rouge Lane, and all the girls in the brothel became eyes and ears. At the age of sixteen, he secretly formed the Killing Sky Pavilion, gathering strange people from all over the world, and fighting against the immortals to fish for luck in the world.
